Hello Frederick, first, just want to ask you if you have a registered developers account? Or are you even a developer? If not, then you should STAY AWAY to iOS 5 GM as much as possible. Anyway, you can follow the tutorial posted below on how to bypass iTunes error 3002:

Step 1: If you are still using iTunes 10.4.1, then uninstall it and download iTunes 10.5 beta 9 for Windows or Mac OS X. Once downloaded, just simply install it on your machine.

Step 2: Once installed, launch the new iTunes 10.5 beta 9 for a while then close it.

Step 4: Then cut and paste the files from above location to your desktop. Do not delete them so that you will be able to put them back in case this tutorial doesn’t work for you. You can find out your username by pressing Ctrl+Alt+Del.

Step 5: Connect your iPhone and then put it in DFU mode:

Press the Home and Power button at the same time for exactly 10 seconds.

Then release the Power button after 10 seconds but continue holding the Home button until iTunes detects your iPhone in DFU mode

Step 6: Finally, proceed with iOS 5 GM restore procedure

That’s it. Hopefully you will be able to restore your iPhone to iOS 5 GM without getting any error. If you want to jailbreak you iPhone on iOS 5 GM, you can also follow our step-by-step guide posted here on how to use Redsn0w 0.9.9b3.
